The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 1.1 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 1.3 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.0002 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.33 SJR: 0.256 SNIP: 0.49 CiteScore™:: 2.4 H-Index: 23

RESUMO

This paper deals with the problem of creeping, steady, axisymmetric Stokes flow of a viscous incompressible micropolar fluid past a Reiner−Rivlin liquid spheroid whose shape deviates a bit from that of a sphere. The polar equation of the deformed sphere is considered for the present study. The stream function solution for the flow outside the liquid spheroid is obtained in terms of modified Bessel functions and Gegenbauer functions, and for the flow inside the liquid spheroid, the stream function solution is obtained by expanding the stream function in terms of S. The flow fields are determined explicitly by matching the boundary conditions at the interface of the micropolar fluid and the liquid spheroid, and uniform velocity at infinity. As an example, the case of an oblate liquid spheroid is considered, and force experienced by it is evaluated. The dependence of drag coefficient on the deformation parameter ε, dimensionless parameter S, viscosities µ1 and µ2, and vortex viscosity κ is discussed for the oblate spheroid and presented graphically. Previous well-known results are then also deduced from the present analysis. It is found that the drag on the oblate spheroid increases with the increase in deformation parameter and cross-viscosity.
